Given numbers are 394, 878, 658, 839

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(394, 878) = 172966

GCD(394, 878) = ( 394 x 878 ) / 172966

= 394 / 878

= 394

Step2:

LCM(2, 658) = 658

GCD(2, 658) = ( 2 x 658 ) / 658

= 2 / 658

= 2

Step3:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

So, Greatest Common Divisor of 394, 878, 658, 839 is 1
